Metals.
Shiny metals that are highly reactive and do not occur naturally by themselves. (They even react with water)
Alkali Metals.
When heat is given off by a reaction or phase change.
Exothermic Change
Changing from solid to gas
Sublimation
The location of protons and neutrons.
Nucleus.
Elements that do not share the properties of metals are known as what?
Nonmetals.
Elements that are reactive metals but not as reactive as the Alkali Metals. (Magnesium for example)

Endothermic Reaction
Changing from gas to solid.
Deposition.
An electron in the outer most electron shell is known as a ____________ election.
Valence.
Columns on the Periodic Table are called:
Families or Groups.
Very reactive non-metals that get darker in color the farther they go down the table and all end in "-ine". (Chlorine)
Halogens.
